Latest Patents

Among his latest patents is the "Digital Integrated Frequency Discriminator of External Clock." This invention features a digital integrated circuit that operates from an external clock signal while incorporating an internal reference oscillator. This design ensures that a reference signal is available as a backup in case the external clock signal is absent or operates at an unsafe frequency. The integrated circuit includes a frequency comparator that evaluates both the external clock signal and the internal reference signal, producing an output that indicates the state of the external clock signal. A two-way switch is employed to select either the external clock signal or the internal reference signal based on the frequency comparator's output.

Another significant patent is the "Microprocessor with Block Move Instruction." This system utilizes a single-chip microcomputer with separate on-chip program and data memory, featuring distinct address and data paths. The architecture allows for off-chip program fetching in an expansion mode, with a bus interchange module facilitating transfers between internal program and data buses. The processor is designed to operate efficiently with various configurations of program and data memory, enhancing its capabilities for digital signal processing applications.
